SHEET-METAL CYLINDER FOR LARD-PRESSES.

SPECIFICATION forming part of Letters Patent No. 769,435, datedSeptember 6, 1904.

Application filed July 7, 1904. Serial No. 215,607. lNo model.)

To all whom it may concern.-

Be it known that I, CLARENCE GREGORY GARRIsUs, a citizen of the UnitedStates, residing at New Britain, in the county of Hartford and State ofConnecticut, have invented a certain new and useful Improvement inSheet- Metal Cylinders for Lard-Presses, &c., of which the following isa specification.

My invention relates to improvements in cylinders for lard-presses orpresses for lard, fruit, or sausage-meat, &c.; and the object of myimprovement is to make the body and bottom of the cylinder from a singlepiece of sheet metal and provide efficient means for attaching the spoutto the said sheet-metal bottom.

In the accompanying drawings, Figure 1 is a plan View of my lard-presscylinder. Fig. 2 is a broken-out side elevation of the same. Fig. 3 is asectional view of the lower part of the same on the line .1 of Fig. 1,and Fig. a is an enlarged detached section on the same line of a portionof the spout in the form that it has before it is attached to the bottomof the cylinder.

A designates a sheet-metal cylinder the sides 5 and bottom 6 of whichare formed of a single piece of sheet metal. A circular hole ispunched'or otherwise cut out of the bottom 6 near its center to receivethe mouth 10 of the spout and to facilitate attaching the spout 7 to thesaid bottom. The spout? is formed of malleable metal, and the mouth 10is provided with a projecting rim 8 of a cylindrical form on its outerside when first formed, as shown in Fig. 4, and having a flange 9surrounding the said rim, with the face of the said flange perpendicularto the outer or cylindrical side of the said rim.

In order to insure a snug fit and to facilitate turning over the rim 8,a milling-tool or sweep is employed to dress off the upper face of theflange 9 and the outer side of the said rim, so that it will snugly litthe hole in the bottom 6, while the top of the flange will closely fitthe under side of the bottom immediately surrounding the said hole. Thesame mill or sweep may also sweep or dress off the inner face of the rim8 inside the mouth, so as to leave a clean surface for the swaging orbending tool. \Vhen the spout has been thus fitted to the bottom, it isfirst secured thereto by rivets 11, passing through the said bottom andflange. After thus securing the spout by rivets the upwardly-projectingportion of the rim 8 is turned over outwardly upon the edge of the metalsurrounding the hole in the bottom, changing the said rim from the formshown in Fig. 4 to that shown in Fig. By

this means a perfectly-tight connection be tween the sheet-metal bottomof the cylinder and the spout may be made which will be efiicient underthe great strain to which such cylinders are subjected.

I claim as my invention A cylinder for lard or analogous presses havinga sheet-metal bottom and a separatelyformed spout, the said spout havinga rim and surrounding flangeat its mouth, with the said rim extendingthrough a hole in the said bottom and the flange resting on the underface of the bottom, the said flange being riveted to the said bottom andthe said rim being turned over inside of the cylinder upon the edge ofthe metal surrounding the said hole in the bottom.
